A launch operator must define a safety clear zone that confines the adverse effects of each operation involving a public hazard or launch location hazard. A launch operator's safety clear zones must satisfy the following:

A launch operator must establish a safety clear zone that accounts for the potential blast, fragment, fire or heat, toxic and other hazardous energy or material potential of the associated systems and operations. A launch operator must base a safety clear zone on the following criteria:

For a possible explosive event, base a safety clear zone on the worst case event, regardless of the fault tolerance of the system;

For a possible toxic event, base a safety clear zone on the worst case event. A launch operator must have procedures in place to maintain public safety in the event toxic releases reach beyond the safety clear zone; and

For a material handling operation, base a safety clear zone on a worst case event for that operation.

A launch operator must establish a safety clear zone when the launch vehicle is in a launch command configuration with the flight safety systems fully operational and on internal power.

A launch operator must establish restrictions that prohibit public access to a safety clear zone during a hazardous operation. A safety clear zone may extend to areas beyond the launch location boundaries if local agreements provide for restricting public access to such areas and a launch operator verifies that the safety clear zone is clear of the public during the hazardous operation.

A launch operator's procedures must verify that the public is outside of a safety clear zone prior to a launch operator beginning a hazardous operation.

A launch operator must control a safety clear zone to ensure no public access during the hazardous operation. Safety clear zone controls include:

Use of security guards and equipment;

Physical barriers; and

Warning signs, and other types of warning devices.
